使用SimpleAdapter填充ListView

本文主要是介绍使用SimpleAdapter填充ListView，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

效果图

1、先定义item

1. <?xml version="1.0" encoding="utf-8"?> 
   <LinearLayout   xmlns:android="http://schemas.android.com/apk/res/android"   android:orientation="horizontal"   android:layout_width="fill_parent"   android:layout_height="wrap_content"> <TextView   android:layout_width="80dip"   android:layout_height="wrap_content" android:id="@+id/personid" />   <TextView   android:layout_width="100dip" android:layout_height="wrap_content" android:id="@+id/name"   
   />    <TextView   android:layout_width="fill_parent"   android:layout_height="wrap_content"   android:id="@+id/amount"   /> 
   </LinearLayout> 

   
   
   

2、通过适配器把数据绑定到listview中，点击某一行数据显示编号

方式一：

1. List<HashMap<String, Object>> data=new ArrayList<HashMap<String,Object>>();   for(Person person :persons){   HashMap<String, Object> hashMap=new HashMap<String, Object>();  hashMap.put("id", person.getPersonId());  hashMap.put("name", person.getName());  hashMap.put("amount", person.getAmount());   data.add(hashMap);  }   
   SimpleAdapter adapter=new SimpleAdapter(this,data,R.layout.item,new String[]{"id","name","amount"},new int[]{R.id.personid,R.id.name,R.id.amount});              listView.setAdapter(adapter);  listView.setOnItemClickListener(new OnItemClickListener(){   
   @Override  
   public void onItemClick(AdapterView<?> parent, View view,  int position, long id) {   ListView myListView=(ListView)parent;  HashMap<String, Object> item=(HashMap<String, Object>)myListView.getItemAtPosition(position);  Toast.makeText(DBActivity.this, item.get("id").toString() , Toast.LENGTH_SHORT).show();  }  }   
   ); 

   
   
   

方式二：用游标的方式

1. Cursor cursor=personService.getCursor(0, 15);        //要求字段中要有_id  设计表的时候的主键为_id          
   SimpleCursorAdapter cursorAdapter=new SimpleCursorAdapter(this,R.layout.item,cursor,new String[]{"_id","name","amount"},new   int[]{R.id.personid,R.id.name,R.id.amount});    
   listView.setAdapter(cursorAdapter);    
   listView.setOnItemClickListener(new OnItemClickListener(){   
   /**   * parent当前所点击的listview对象   * view当前所点击的条目   
   */   
   @Override   public void onItemClick(AdapterView<?> parent, View view,  int position, long id) {   ListView myListView=(ListView)parent;  Cursor data=(Cursor)myListView.getItemAtPosition(position);//根据位置移动游标  int m=data.getInt(data.getColumnIndex("_id"));   Toast.makeText(DBActivity.this, String.valueOf(m) , Toast.LENGTH_SHORT).show();  }  }  
   );
